Configuration

Import the latest .gsd file into your Master configuration tool. This file is available from santerno.com

.

If your Master uses on-screen icons, two graphic bitmap files are available from the website. SSPM_N.bmp indicates normal mode.

SSPM_D.bmp indicates diagnostic mode.

NOTE

The Profibus Module has a slave address range of 0 to 99.

If the Profibus network fails, the module will leave data exchange mode after the network watchdog timeout period has expired. This timeout period is set at the Master configuration tool.

A Communication Timeout parameter in the GSD file sets how soon after this event the soft starter will be forced into a trip state.

The user can adjust the Communication Timeout parameter in the GSD file to any setting between 0 and 100 seconds. The default setting is 10 seconds.

NOTE

If the Communication Timeout parameter is set to 0, the current state of the soft starter will remain unchanged on a network failure. This gives the user the option of operating the soft starter via local control, but is NOT failsafe.

Adjustment

Before powering up the Profibus Module, set the two rotary switches so that the module address matches the address set in your Master configuration tool. eg MSD = 2 and LSD = 1 corresponds to address 21.

(The diagram shows the factory default setting for the rotary switches).

The module automatically detects the network data rate.

5. Connection

The module connects to the Profibus network via a standard DB9 connector.

The Profibus Module can be powered either through the network cable or externally (24 VDC).

ASAC: For the Profibus Module to accept serial commands, a link must be fitted across terminals A1-02 on the soft starter.

ASAB: Input links are required across the stop and reset inputs if the soft starter is being operated in Remote mode. In Local mode, links are not required.

NOTE

ASAB: Parameter Comms in Remote selects whether the soft starter will accept Start and Stop commands from the

Serial Network Master while in Remote Mode. Refer to the soft starter user manual for parameter details.

NOTE

If communication fails between the module and the network, the Bus Status LED will go off. When communication is restored, the Bus Status LED will come back on.

NOTE

When a communications failure occurs, the soft starter may trip if the Communication Timeout parameter for the network is set greater than zero. When communication is restored, the soft starter must be reset.
